   EXPERTISE — MOBILE FALLBACK
   The pinned photo + percentage-positioned hotspots are
   calibrated for a wide desktop crop and a 5000px scroll-jack
   that both break down on a phone. Below 768px we swap the
   whole interaction for a photography-free, typography-led
   layout, reusing two motifs already proven elsewhere on this
   site: the oversized translucent chapter numeral from
   projects.html (.pall-ghost-num) and the numbered gold-dot
   service rows from the Process section (.process-step). No
   image means no aspect-ratio cropping, no gradient-legibility
   balancing act, and nothing for the back-to-top button to
   visually clash with.
